Andrew House, president and chief executive of Sony Computer Entertainment, introduces the PlayStation 4 in New York.

Sony Corp. revealed quite a few details about its new PlayStation 4 on Wednesday in New York. (You can see what it said in our live blog and roundup. ) So, what are the remaining big questions surrounding the new game console, slated for release in “holiday 2013.”

1) How much will it cost?

This is always a thorny issue with a new game machine. Price it too low and the company risks building a mountain of losses since many videogame hardware makers lose money, at least initially. Price it too high and you scare off consumers.

This is a particularly sensitive issue for Sony, which stunned consumers with the initial $500 and $600 price tag for the PlayStation 3. Even at those prices it was losing a lot of money. That price tag hurt the PS3’s early adoption and gave an advantage to Microsoft Corp. and Nintendo Co.’s rival machines.
